To all whom it may concern:

Be it known that I, HARRY" CHARLES GAMAGE, a citizen of theUnitedStates, residing at the city of New York, in the county of NewYork and State of New York, have invented a certain'new and usefulImprovement in Lubricating Devices for Shafts, &c., of which thefollowing is a specification.

' The invention relates tollubricating devices for rotary shafts, andhas for its object to simplify construction and insure more perfectlubrication.

The device is herein illustrated in an embodiment more especiallydesigned for the lubrication of car axles,'in which the lubricantcontained in a suitable vessel, such as the axle box, is intermittentlytransferred from said box to an exposed side of the journal, by means ofa vibrating arm, prefer-' ably provided with a plate at its end, whichraises or throws said lubricant to said journal surface. It is notessential that the arm or i plate'shall actually touch said surface,since its path of vibration may terminate at a distance therefrom overwhich interval the lubricant may be project'edand this result isassisted by making the arm a spring or actu ating it by resilientmechanism, or as herein shown, by adopting both expedients, Theconstruction is also such that although the arm is operated bythe'rotation of the'shaft, longitudinal play of the shaft in its bearing.is permitted and transmission thereof to said arm prevented. y

In the accompanying drawingsFigure 1 is a section of a car axle boxshowing my device in position, taken on the line '1, l, of Fig. 2. Fig.2 is a section on the line 2, 2, of Fig. 1. Figs. 3 and 4 show thegearbox in detail, Fig. 3 being a section on the line 3, 3, of Fig. 4, andFig. 4 beinga section on the line 4, 4, of Fig. 3. 4

Similar letters "of reference indicate like parts. I

The car axle box A, axle B and bearing 0, are all of the usual pattern.Resting on the bottom of the box is a metalframe having side members Dand transverse member E, the side members being curved near their endsto suit the inner curvature of the front of the box and the transversemember E resting against the rear wall of said box. Pivoted to each sidemember are two bars F, G,

which meet at their upper ends and are connected' by pins H. A lightframe fitting 1 within the'box is thus provided, on the side members Dof which, near their front ends, is supported a rod I on which is a longsleeve J, from which extend rearwardly two parallel plates K. A leafspring arm L is secured at its end between said plates. Said spring armextends beneath the axle journal,

and near its rear extremity has an opening through which passes a lug onthe bottom of a metal plate M, saidlug being secured in the opening by atransverse pin on the under side of the plate. Any other convenientmeans of attaching the plate M to the spring arm L may be used. When theplate is in the position shown in Figs. 1 and 2, it is submerged in oilcontained in the axle box.

In the end of the axle A is tapped a threaded hole to receive a threadedhollow rod N, provided with a flared flange O, which is received in acorrespondingly formed countersink in the axle. Said rod carries a wormP and is received in bearings formed in both sections of a two part boxQ, the sections of said box being flanged and connected by boltsand nutsas shown in Fig. 4. J ournaled in said box is a shaft R carrying'apinion S engaging with worm P 'X, which loosely enter openings in theupwardly projectingarms of a frame Y, the horizontal connecting memberof which passes beneath'spring 'arm L and is secured in place by rivetswhich also serve to fasten said armbetween' the plates K.

The operation ofthe device is as follows:

Motion is communicated from the rotating axle A to the worm P and so topinion S and crank disks T; From said disks through the frame U, springV and block W, the spring leaf arm L is swung intermittently upward, asindicated by the arrows in Fig. 1. The plate M, is thus caused to dashoil upward and against the under side of the axle journal, thusproviding an ample sup ply of lubricant to the bearing. The faster theaxle rotates, the more numerous the swings of the plate M per giventime, and hence the greater the quantity of lubricant delivered. Theinterposition of the elliptical springbetween the crank disk-(T andEspecial attention is called to the jointformed between the arm L andframe V by the loosely fitting pins X entering frame Y. This permitslongitudinal play of the axle B in its bearing without transmitting saidmovement to said arm.

I claim:

1. In a shaft lubricator and in combination with the shaft journal, avessel for holding lubricant, and, in said vessel, a vibrating arm forintermlttently throwing said lubricant from said vessel to said shaftjournal.

2. The combinationof a-rotary shafthaving longitudinal play in itsbearing, a device for applying lubricant to said shaft, and mechanismfor transmitting motion from said shaft to actuate saiddevice; the saidtransmitting mechanism being operated by the rotation of said shaft andconstructed to permit longitudinal play of said shaft in both directionsand in all positions of said device without transmitting said movementto said device.
